Answer:
400
Step-by-step explanation:
Calculation to determine the economic order quantity is using the basic EOQ model,
Using this formula
EOQ=√(2[Demand][Order cost] / [Unit holding cost])
Where,
Demand=320
Order cost =$1,000
Unit holding cost =$4
Let plug in the formula
EOQ=√2*320*1,000/$4
EOQ=√640,000/$4
EOQ=√160,000
EOQ=400
Therefore the economic order quantity is using the basic EOQ model is 400
